Case001 / Suma Gestión

Replaced eight spreadsheets with one system.

01 — Problem.A 40 person SMB was running stock, billing and customers across separate spreadsheets. Double entry, lost invoices, outdated inventory.

02 — Tech decision.Go + React monolith. No unnecessary microservices. One deploy, one database, docs the client can actually read.

03 — Outcome.AFIP invoicing shipped in week 4. Two months after launch, zero critical tickets. Still in daily use.

FAQ

Reasonable questions.

If something isn't here, write us. We reply directly.

01

Do you work with in-house teams?

Yes. We plug into your Slack, Jira or whatever you use. Our PRs get the same review as anyone else's.

02

Do you offer post-delivery maintenance?

We include 3 months at no extra cost. After that you can move to retainer or handle it internally with the docs we leave.

03

Who owns the code?

You do. From commit one, in your repo, under your license. We never reuse one client's code on another project.

04

What if I have less budget?

We tell you what fits and what doesn't. We'd rather ship something smaller but finished than inflate an MVP you won't use.

05

Why don't you take more than two projects at once?

Because doing one well takes us 40 hours a week. We tried multiplying and quality drops.
