Discovery
We map today's process, systems and data for sales and invoice posting; inventory and purchase; and returns and credit notes, talk to the people who run it and agree the baseline for month-end close time and stock mismatch so progress is measured from week one.
Design
We design the flows, roles, approvals and integrations for sales and invoice posting; and inventory and purchase, and review a clickable prototype with the people who will use it before anything is built.
Build in weekly demos
We build in weekly demos, starting with sales and invoice posting, then inventory and purchase and returns and credit notes. Each release is tested on your own data and passes a human approval gate before the next begins.
Launch and support
We migrate data, train your team and support go-live. After 30 days we review month-end close time, stock mismatch and return processing time against the baseline and agree what to extend next.
Start small. Scale when it works.
Every engagement begins with a short, fixed-price step so you can judge the fit before committing further. See pricing.

Unicommerce Integration questions.
Which ERPs do you integrate with?
Tally, Zoho, SAP Business One, custom ERPs and others with usable interfaces. We confirm yours in discovery. We confirm versions, plans and API limits during discovery, so there are no surprises on integration day.
Does Unicommerce expose APIs for this?
Interfaces depend on your plan and set-up. We confirm what is available before committing to scope.
Can it post invoice-level data to Tally?
Yes, either at invoice level or as summarised vouchers, depending on what your accountant prefers. Your accountant reviews the ledger mappings before anything posts, and every posting is logged and traceable.
How do you avoid duplicate postings?
With idempotent posting, unique references and an exception queue.
How soon can we start?
With a two-week Discovery Sprint to confirm interfaces, mappings and timeline. We agree milestones up front and show working software every week, so any delay is visible early and handled openly.
How much does Unicommerce integration cost?
Every engagement starts with a fixed-price Discovery Sprint that produces scope, a plan and a quote. Custom work is quoted at a fixed price once the scope is clear. Changes are agreed in writing before they are built, so the price you approve is the price you pay.
How do you measure success for Unicommerce integration?
In week one we agree a baseline for month-end close time, stock mismatch and return processing time. We report them at every weekly demo and review them against the baseline 30 days after go-live, so results are measured rather than assumed.
What should we prepare before the first call?
Bring a short description of how Unicommerce integration works today, examples of the documents or screens your team uses, and the three numbers that matter most to you. A senior specialist will use them to outline a first step and a fixed price.
