Two things cause the most friction in project-based delivery: unclear scope and money paid too fast. We put both up front — deliverables listed item by item, acceptance criteria tested one by one, and payment tied to milestones. Raise any dissatisfaction before the payment gate, not at the very end.
Fixed scope, fixed deliverables, fixed timeline. Before signing, we produce a "Scope & Deliverables List" signed by both parties; later scope changes go through change orders, and no extra charge for parts that don't add cost.
Engaged by the person-day or month, plugged into your dev environment and standups — effectively an external software group. Fits projects where requirements keep changing and scope can't be fixed once.
An annual framework agreement with 5 reserved person-days per month, usable across projects; unit prices below single-project rates. Fits companies with multiple machines and ongoing retrofit needs.
Engaged through integrator subcontracting or third-party platforms, settled under their rules. Fits remote clients starting with a small trial order before moving to direct collaboration.
Why we hold the last 10% until after acceptance: it's a small amount, but it's proof we stand with you — if the deliverables don't meet the standard in the contract, you can withhold that 10% and we have no grounds to press for it. Conversely, if acceptance passes and payment still drags, we pause subsequent services (also written into the contract, applying to both sides equally).
Remote projects have no "site entry" milestone, so the corresponding 40% is paid against staged deliverables: half on completion of the structure mapping, half on completion of the main delivery. The proportions match on-site projects.
No "good quality" or "looks nice" clauses that can't be measured — every criterion maps to an executable action.
| Delivery type | Acceptance method | Pass criteria |
|---|---|---|
| Program refactoring | Station-by-station motion verification + item-by-item confirmation of the behavior difference list | All differences in the list confirmed by the client; no new unexpected behavior |
| Documentation | The client's maintenance engineer completes one fault-localization using only the docs | Able to locate the block and signal without looking at the program |
| Localization | Screen-by-screen screenshot comparison + 10% terminology spot-check | No overflow/truncation; 100% terminology consistency |
| HMI/SCADA application | Item-by-item testing against the point list and report definitions | Acquisition accuracy and refresh cycle meet spec; report figures match manual reconciliation |
| AI pilot | Comparison against the manually labeled baseline | Hit rate and false-positive rate within contractually agreed bounds |
Custom development results (including source code and docs) belong to the client once payment is settled in full. We retain ownership of generic components, templates, and tools, but grant the client a perpetual, royalty-free, transferable license — so switching vendors won't leave you stuck.
Go through a change order: state what's added, the schedule impact, and the cost impact, and execute after both sides confirm. Small adjustments that don't affect the deliverables list are free (we reserve about 10% slack in every project).
Software deliverables carry a default 90-day warranty: problems caused by defects in our deliverables are fixed free of charge during that period. After the warranty, maintenance is by incident or annual. Problems caused by the client's own changes, third-party changes, or hardware faults are outside warranty, but we can assist in troubleshooting by the hour.
Yes — we issue VAT invoices (standard or special) and accept corporate bank transfer. With contract, quotation, and acceptance record in order, there's no issue running it through your procurement process.
We sign an NDA: programs, drawings, process parameters, and client information are all confidential, and copies are deleted or returned at project close. If needed, we can accept non-compete terms (same city and industry, no similar projects within the agreed scope).
