04 · How we work

Four phases. Fixed price.

We’ll come back with a written scope after the first call — no airy retainers, no scope creep. Built so a partner-level reviewer can sign off on the output without flinching.

Phase 01

Discover

A 45-minute call. Show us your Tally, your Excel sheets, the spreadsheets-of-spreadsheets. We’ll map every report you actually use.

Week 01 · free
Phase 02

Map

A written scope: deliverables, data sources, owners, edge cases, and a wireframe of every screen. You sign off before we build.

Week 01–02
Phase 03

Build

We build in your test environment with weekly demos. Tally TDLs are deployed in a parallel folder so your live install is never touched.

Week 02–05
Phase 04

Hand off

A week of parallel runs against your old reports. Documentation, video walkthroughs, and a 30-day warranty on every line of code.

Week 05–06

07 · About

Why Zero Lag.

A small studio with a sharp focus: data plumbing for finance, audit and revenue teams. We’re the ones you call when the workbook starts to break.

“Every finance team has a workbook held together with tape, copy-paste, and the fear of one person leaving. Our job is to replace it with something you’d show a client.”
01

Domain-first, code-second

We speak debit-credit and TDL before we speak frameworks. The first conversation is about your ledger, not our stack.

02

Fixed scope. Fixed price.

You get a written scope before we build. No hourly billing surprises. No phantom retainers. If it’s outside scope, we’ll say so.

03

Documented, never “black-boxed”

Every Tally TDL, every script, every dashboard ships with a one-page operator manual and a video walkthrough. Your team owns it.

04

Audit-grade by default

Versioned code, signed releases, parallel-run validation. Built so a partner-level reviewer can sign off on the output without flinching.

Got a workbook that’s breaking?

Send it over. We’ll come back within one working day with three ideas — what to automate first, what to leave alone, and what we’d charge to ship it.
