Ask a mid-market CFO to draw their software stack and you'll get the same picture almost every time: a CRM, an accounting system, an HR platform, a cap-table tool, a sales-engagement tool, a marketing suite, a notetaker — seven to ten systems, each excellent alone, connected by a lattice of integrations, sync jobs, CSV exports, and one overworked ops person.
A Company OS is the alternative architecture: one platform where revenue, money, people, and ownership live on a single governed data layer, so the products don't integrate with each other — they simply read the same records.
The stitching problem, quantified
The pain isn't any single tool. It's the seams between them:
- The same fact exists in five places. A customer is a record in the CRM, a counterparty in accounting, a logo in the marketing suite, a transcript tag in the notetaker. When they change entities or terms, someone reconciles.
- Integrations are a second product you maintain. Field mappings break on vendor updates, sync jobs fail silently, and the answer to "which system is right?" is a meeting.
- AI can't see across the seams. An AI SDR that can't see accounts receivable will cheerfully pitch a customer your books flagged 60 days past due. Per-app AI assistants inherit per-app blind spots.
- You pay for the overlap. Each tool carries its own admin, its own per-seat pricing, its own contract cycle.
For a company between roughly $10M and $500M in revenue, the stitched stack commonly runs six figures a year before you count the ops time spent tending it.
What makes something a Company OS (and not just a suite)
Plenty of vendors sell multiple products. The test is what's underneath:
- One data core, not an integration bus. In a Company OS, a customer, invoice, employee, or share exists exactly once. Products share data by reading the same records — no connectors, no event sync, no export-import. In Interlock's case this is the Common Data Core: one schema, one event bus, row-level tenancy.
- AI that operates on the whole company. Because the data is unified, agents can be too. Interlock ships a virtual executive team — vCEO, vCRO, vCFO, vCHRO, vCMO — that hands back finished work rather than per-app suggestions, because each agent sees revenue, money, and people in the same query.
- One security and compliance boundary. A stitched stack has ten vendors' security postures; your auditor gets to review all of them. One platform means one posture — Interlock's is coded to SOC 2 Type II, HITRUST CSF r2, and FedRAMP High standards and audit-ready for all three (certifications in progress).
- Pricing that rewards consolidation. The economics should get better as you consolidate, not worse. Interlock's bundles discount 20% for two products up to 50% for all seven — the full stack lists at $6,776/mo à la carte and $3,388/mo on Interlock Complete.
Honest trade-offs: when a Company OS is the wrong call
Calibration matters more than enthusiasm, so here is where the stitched stack genuinely wins:
- Best-of-breed depth in one function. If your business is its channel program or its dialer, a specialist (Impartner, Outreach) will out-feature the integrated equivalent. We say the same on every product comparison page — Salesforce wins on AppExchange depth, Carta on its investor network, NetSuite on ERP breadth.
- Deep sunk investment. A Salesforce org with a decade of custom objects and a consulting bench is expensive to leave. The migration cost is real and should be priced into the decision.
- Under ~20 employees. A micro-business does fine on QuickBooks and a spreadsheet. The Company OS case starts when the seams start costing headcount.
- Needs outside the OS's scope. Inventory, manufacturing, field service — if you need ERP breadth, you need an ERP.
| Stitched stack | Company OS | |
|---|---|---|
| Data | Same fact in 5+ systems, reconciled by people | One record, read by every product |
| Integrations | Built, monitored, and repaired by you | None between products |
| AI | Per-app assistants with per-app blind spots | Agents that see the whole company |
| Security reviews | One per vendor | One, total |
| Cost curve | Grows per tool, per seat, per contract | Bundle discounts grow with consolidation, 20–50% |
| Best-of-breed depth | Wins — specialists out-feature suites in their lane | Good-to-great per product, unified |
What a Company OS costs
Interlock prices each product for the mid-market — full price book here — and every self-serve tier starts with a 14-day free trial. Three reference points:
- CRM (Elevate): $49–99 per user/month, AI included from the first tier.
- Accounting (Ledger): $299–999 flat/month, multi-entity consolidation at the top tier.
- The whole OS (Interlock Complete): all seven priced products at 50% off list; a 3-year term compounds a further 25% off.
How to evaluate one
- Count your seams. List every integration, sync job, and recurring export between your systems, and who fixes each when it breaks. That's the tax you're currently paying.
- Ask where the record lives. For any vendor claiming "unified," ask: if I change a customer's name, how many systems store it? One is an OS; more is a suite with connectors.
- Test the AI across functions. Ask the platform's agents a question that spans revenue and finance ("which of my top-10 pipeline accounts are behind on invoices?"). Per-app AI can't answer it.
- Price the exit, both ways. Leaving your current stack has a cost; so does staying. Put numbers on both before deciding.
The stitched stack was the only option for twenty years. It isn't anymore — and the mid-market, which never had enterprise integration budgets in the first place, is where the replacement starts.
