Why UK businesses choose Gimpact
- 01
Four to five hours of overlap
We are UTC+5 — four hours ahead of London in winter, five in summer. Our afternoon is your morning, so stand-ups, reviews and calls sit comfortably inside both working days: no fixed single window, no waiting overnight for an answer.
- 02
UK GDPR designed in
Lawful basis, data minimisation, retention periods, subject access and deletion are design decisions we make with you at the start, not a policy page written at launch. We work to your DPO's requirements and do not offer legal opinions of our own.
- 03
The payment rails you actually use
Stripe for cards, GoCardless and Bacs for direct debit, Faster Payments and Open Banking where it is cheaper than cards. Subscription and invoicing logic is built for how UK businesses really bill.
- 04
It has to fit the finance stack
Systems that create invoices integrate with Xero, QuickBooks or Sage and produce data suitable for Making Tax Digital submissions, so VAT reporting is not a re-keying exercise for your bookkeeper.
- 05
Senior engineers, direct contact
You talk to the people writing the code. No account manager layer, and no team you never meet being swapped out behind the scenes.
- 06
You own everything
Code, cloud accounts and third-party services in your company's name from the first commit, with documentation and tests good enough for your own team to take over.
The market we are building for
The UK is one of the easiest markets for us to serve well, for an unglamorous reason: the working day genuinely overlaps. We are UTC+5, so our afternoon is London's morning and there are five or more hours in which a question can be asked and answered the same day. That removes most of the friction people associate with remote engineering teams.
Two things shape the technical work more than anything else. UK GDPR is a design input rather than a document — lawful basis, retention, subject access and deletion have to be decided while the schema is being written, because retrofitting them into a live system is expensive. And the finance stack matters: an invoicing feature that does not reconcile with Xero, QuickBooks or Sage, or that produces data unsuitable for Making Tax Digital, creates work rather than removing it.
We are a supplier, not an adviser on your obligations. We build to what your DPO, accountants and legal counsel require and we say clearly where our responsibility ends. That boundary is easier to state now than to argue about later.
Market and regulatory context is provided for orientation, not as legal, tax or compliance advice. Confirm specifics with your own advisors — we build to the requirements you set.

Frequently asked questions
Questions from this market
No. Gimpact operates from Uzbekistan and works with UK clients remotely — we will not claim a London presence we do not have. What we do have is four to five hours of daily overlap with UK working hours, which is the part that actually affects how a project runs.
Data lives in the region you choose, in your own cloud account — normally a UK or EU region on AWS, Google Cloud or Azure. Lawful basis, minimisation, retention and deletion are designed in while the schema is written, and subject access and erasure are built as working features rather than manual database work. We are a processor acting on your instructions and we work to your DPO's requirements; we do not give legal advice or certify compliance.
Yes, and for most UK projects it is the integration that decides whether the system is actually adopted. Invoices, credit notes, payments and reconciliation flow both ways so your bookkeeper is not re-entering anything, and the data is structured to suit Making Tax Digital submissions. Final VAT treatment stays with your accountant.
We are UTC+5, four or five hours ahead of London depending on the time of year. Our afternoon is your morning, which gives four hours of overlap in winter and five in summer, enough for stand-ups, reviews and calls to fit inside both working days. Unlike our US clients, you do not need a single fixed window — a question asked in your morning is answered in your morning.
A written scope and estimate first, then a phased contract with milestone invoicing in GBP or USD by international transfer. We can work under your own contract, NDA and IP assignment, and the phased structure means you can stop at any milestone boundary rather than committing to the whole build up front.
