Replace Spreadsheets
When a critical process lives in a spreadsheet — quoting, inventory, scheduling, compliance — you inherit version conflicts, manual reconciliation, no audit trail, and one person who understands the formulas. Slingr turns it into a custom app you own.
The hidden cost
Five copies, three versions, and nobody's sure which is current. Decisions get made on stale numbers and reconciled by hand.
The logic lives in one person's head and one fragile file. When they're out — or gone — the process stops.
A wrong cell, a broken reference, a silent overwrite. There's no record of who changed what, which is a liability the moment an auditor or customer asks.
What we build
We keep the logic your team already trusts and build it into a real application — multi-user, validated, audit-ready, and integrated with your other systems.
The formulas and workflows become validated logic the app enforces — no broken references, no overwriting the master copy.
Everyone works from one source of truth, with permissions, history, and a clear record of who changed what.
Pulls from and pushes to your other systems instead of living as an island that someone re-keys every morning.
Built in weeks at roughly 50–60% of traditional cost, owned outright — no per-seat SaaS to replace the spreadsheet you outgrew.
Questions teams ask
When spreadsheets are running a real business process — quoting, inventory, scheduling, compliance — and the manual reconciliation, version conflicts, and key-person risk start costing more than the tool saves.
Not anymore. AI-accelerated development makes a purpose-built app affordable at roughly 50-60% of traditional cost — and you own it, with real validation, audit trails, and multi-user access spreadsheets can't give you.
Yes. We map the formulas, rules, and workflows your team relies on and build them into a system that enforces them — no more broken references or someone overwriting the master copy.
AI-accelerated pods ship working software in weeks, not quarters — you'll have a usable app early and iterate from there.
Describe the process the spreadsheet runs today and get a budgetary scope back the same day. You'll own the app that replaces it.
