Prompt Strategy

n8n, Make.com and Zapier automation with AI steps and a human approval check — fixed price, documented on handover.

What Are Prompt Engineering Services?

Prompt engineering services turn ad hoc AI instructions into a documented system: goals, context, constraints and output rules written down, tested against real inputs and kept under version control. Our prompt strategy team in Dhaka, Bangladesh, builds that system for US, UK and Singapore companies and hands over the prompt library, test sets and documentation in accounts you own.

Delivered from Dhaka (UTC+6): a four-day audit, then a pilot you judge on your own test inputs before the library is built.
Fixed prices with scope caps: a $300 audit, then a $600 pilot · See pricing →
4 days Prompt Audit $300 up to 10 prompts
2–3 weeks Pilot $600 for one workflow
With the pilot Library setup $899 fixed
Monthly Prompt Desk $999 up to 10 updates

Who is prompt strategy for?

Prompt strategy suits any team whose AI output changes from one run to the next. Three buyer types hire us most, and each gets the same system tuned to a different job.

Marketing and content teams

Every writer prompts differently, so the output does too. You get one shared prompt library with templates for each content type, tested against your own examples and versioned as you refine it.

Support and operations teams

A reply that varies by run is a support risk. You get prompts with fixed output structures, defined refusal and escalation rules, and a test set you can re-run before anything ships.

Product and AI teams

Prompts live in your codebase and break on model updates. You get versioned prompt files, a documented test set, and a re-test when a model version you use changes.

What prompt engineering services include

Our prompt engineering services deliver six things every time. You get a use case and goal map, a prompt architecture, custom prompt development, prompt testing against a test set with written evaluation criteria, a versioned prompt library, and documentation with handover. Prompt optimisation continues from there, against the same criteria rather than by feel. You receive a working prompt system, not a list of tips.

 

Use case and goal map

A written map of the tasks you want AI to do, what a good output looks like for each, and which ones are worth a prompt at all.

 

Prompt architecture

How each prompt is put together: system instruction, context you supply, task, constraints and the output format the next step expects.

 

Custom prompt development

The prompts themselves, written for your data and your wording, with the reusable parts split out as templates your team can fill in.

 

Test set and evaluation

A set of real inputs with the output you would accept for each, plus written pass and fail criteria, so a prompt change can be judged instead of argued about.

 

Prompt library with versions

Every prompt stored in one place with a version number, what changed, who changed it and which test run it last passed.

 

Documentation and handover

Written notes on why each prompt is built the way it is, how to change it safely, and a walkthrough for the people who will own it.

Not included: model fine-tuning or training · AI model and API usage fees, paid by you to the provider · application or agent development, which is a separate build · guaranteed accuracy, ranking or cost-saving figures · scope above the published caps, quoted before the work starts.

Which use cases do you cover?

Content Briefs, drafts, product descriptions and repurposing, each with a fixed structure and a house voice the prompt enforces.
Support Ticket summaries, draft replies, tone rules and escalation wording, with refusal cases written into the prompt.
Operations Document extraction, classification, routing rules and summaries, returned as structured output another system can read.
Sales Research briefs, call summaries and follow-up drafts, built from fields your CRM already holds.

Which models do you work with?

Models Whichever your team already pays for, such as ChatGPT, Claude or Gemini, running on your own accounts and API keys.
Portability Prompts are written to be readable on any of them, and the test set shows what changes when you switch.
Where they live Your drive, Notion, repository or the tool that calls them, through named accounts that you create.
Reporting A shared Slack, Teams or email channel, plus a monthly note on what changed and what the tests showed.

How does the prompt build work?

Our prompt engineering services run in four fixed-price steps, each with a published scope cap: a four-day prompt audit ($300, up to 10 existing prompts), a two-to-three-week pilot ($600, one workflow and up to 5 production prompts), the prompt library setup ($899, built alongside the pilot) and an optional Managed Prompt Desk ($999 a month, up to 10 prompt updates). Adoption is not the gap: CMI’s 2026 B2B survey of 1,015 marketers found 89% already use AI content tools, while only 39% saw performance improve. The instructions, not the tools, are usually what is missing.

Why choose Eicra for prompt engineering?

Prompt engineering services design, test and document the instructions your business gives an AI model. We work test-first because the EBU and BBC study of 3,000 AI answers found 45% carried at least one significant issue. Prices are published with scope caps, every prompt is judged against a test set you agreed, and all work stays in accounts you own.

Published fixed prices — every step is priced before you start, from the $300 audit to the Managed Prompt Desk at $999 a month.
Scope caps, not guesses — every package states the prompts and use cases it covers, so the work does not quietly thin out.
Judged on a test set — prompts are accepted against real inputs and written criteria you agreed, not on how the demo felt.
Built for model change — prompts are written to be portable, and the desk re-runs your test set when a model version you use changes.
You own everything — the prompts, templates, test sets and documentation live in your accounts, and our access ends with the engagement.
Named contracts — GDPR Article 28(3) processor terms, the ICO IDTA or UK Addendum for UK clients, and PDPA-compliant clauses for Singapore.

Is it safe to outsource prompt work?

Outsourcing prompt work is safe when the safeguards are agreed in writing first. The main risks are your business logic and sample data leaking, lock-in, and prompts nobody internally understands; IBM’s 2025 breach report found 97% of organisations with an AI model or application breach lacked proper AI access controls. Every engagement opens with a mutual NDA, named least-privilege accounts and a data processing agreement, prompts and test data stay inside your own systems, and the documentation exists so your team can take over.

Contracts and transfers

Which agreements are signed, and when?

NDA — mutual, signed before we see a prompt or a sample input.
DPA — the processor terms required by Article 28(3) of the GDPR and the UK GDPR, for any personal information.
UK clients — the ICO’s International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses.
Singapore clients — contract clauses that meet the PDPA Transfer Limitation Obligation (section 26), based on the ASEAN Model Contractual Clauses.
US clients — SOC 2 readiness roadmap available on request; certifications are listed only when held.
Access, IP and service levels

What access and rework terms apply?

Access Named least-privilege accounts that you create, and we work from redacted sample inputs wherever possible.
Ownership The prompts, templates, test sets and documentation are yours; we keep no copies.
SLA Response and update times for the desk, stated in the signed terms.
Rework Free when a prompt fails the agreed test criteria; new scope is priced first as a change request.

Common questions about prompt strategy

How much does this cost? See pricing →

How much do prompt engineering services cost?

With Eicra Soft, a first engagement costs a fixed $1,799: $300 for the prompt audit (up to 10 existing prompts, one use case), $600 for the pilot (one workflow, up to 5 production prompts) and $899 for the prompt library setup, built alongside the pilot. After that the Managed Prompt Desk is $999 a month for up to 10 prompt updates. For comparison, Upwork publishes a median AI engineer rate of $50 an hour, and Fiverr prompt gigs start around $15 with no testing or documentation.

How long does a prompt build take?

A first engagement is live in about four weeks: a four-day audit, then a two-to-three-week pilot with the library setup built alongside it. Once the desk is running, prompt updates are delivered inside the monthly allowance. Delivery from Dhaka (UTC+6) gives overnight turnaround for US teams and same-day for the UK and Singapore.

What is a prompt strategy exactly?

A prompt strategy is the system around your AI instructions rather than the instructions themselves. It covers which business tasks are worth prompting, how each prompt is structured, what context it receives, what output format it must return, how it is tested, how versions are tracked and who maintains it. The deliverable is a prompt library with test sets and documentation, not a list of clever phrases.

How is this different from prompt writing?

One-off prompt writing gives you a phrase that worked once for one person. A prompt strategy gives you templates anyone on the team can run, a test set that says whether a change made things better or worse, version history, and documentation so the person who wrote it is not the only one who can maintain it. The difference shows up when the author leaves or the model updates.

What happens when a model updates?

Prompts that were tuned to one model version can behave differently on the next. That is why the test set exists. Under the Managed Prompt Desk, when a model version you use changes we re-run your test set on the new version and report which prompts behave differently, then fix the ones that matter within the monthly update allowance. Without the desk, you still hold the test set and can run it yourself.

Can you guarantee better AI output?

No, and be careful with anyone who does. We do not publish accuracy percentages, hallucination-reduction figures or ROI guarantees, because the result depends on your data, your model and your use case. What we do commit to is testable: prompts are accepted against a test set and written criteria you agreed before the build, and rework is free when a prompt fails them.

How do you test a prompt?

1. We collect 20 real inputs from your own work, including the awkward ones. 2. You define what an acceptable output looks like for each, in writing. 3. The prompt is run across all 20 and the results are scored against those criteria. 4. Failures are diagnosed as a prompt problem, a context problem or a model limit, and the prompt is revised. 5. The test set ships with the prompt so the same check can be repeated later.

What happens above the scope caps?

Every package has a published cap: 10 prompts and one use case for the audit, one workflow and 5 production prompts for the pilot, 15 templates across 3 use cases for the library, and 10 updates a month for the desk. More use cases, more prompts or an embedded engineer are quoted as a custom engagement after the audit, priced in writing before any work starts. The caps are deliberate, because a prompt that is written but never tested is not a deliverable.

Who owns the prompts you build?

Your company does, from day one. The prompt templates, system instructions, test sets, evaluation criteria, version history and written documentation live in your own drive or workspace, and we build inside your accounts rather than ours. At handover you keep every file, our access is removed, and nothing is retained on our side. There is no platform to stay subscribed to in order to keep using what you paid for.

What access do you need?

Less than most people expect. We need sample inputs and outputs for the use case, your written quality criteria, and access to the AI tool account only if you want prompts tested in your own environment rather than ours. You create any accounts in your own name, grant access for the engagement, and we remove it at handover. Work starts after a mutual NDA, personal data is handled under a data processing agreement, and no sub-processor is added without your written approval.

Can you take over existing prompts?

Yes, and the audit is built for it. We read the prompts your team or a previous provider already wrote, record where each one fails and why, and rebuild the ones worth keeping as documented templates with a test set. You keep the audit findings and the rewritten templates whether or not you continue with us, so nothing you have already paid for is thrown away.

What is outside the scope?

Prompt work is not model training, and it is not application development. We do not fine-tune or host models, build RAG pipelines or agent infrastructure, or write the software that calls your prompts, which is AI agent development and AI integrations work rather than prompt work, and we do not sign off on legal, medical or financial output that a licensed professional has to approve. Where a use case needs engineering rather than prompting, the audit says so in writing instead of selling you a prompt library that cannot fix it.

Start with a four-day prompt audit, $300 fixed. You leave with a written review of up to 10 existing prompts, the failure patterns behind them and a fixed quote for the pilot, whether or not you go further with us.
