# Honest Alternatives to the Big ERP and CRM Vendors

In short: 10 migration guides, each comparing one incumbent against a custom system you own completely — no rigid per-seat licensing, no vendor lock-in, no maintenance overhead you cannot cancel. Every pricing figure, licensing limit and API ceiling here carries a link to the vendor's own documentation, and every page names something the incumbent genuinely does better, because a comparison that concedes nothing is an advertisement. Oracle NetSuite, SAP S/4HANA, Microsoft Dynamics 365, Salesforce, Odoo, Epicor, Sage X3, Zoho Creator, monday.com and HubSpot are covered.

## Frequently asked questions

### When is a custom build genuinely better than a licensed ERP?

When the process is the product. The licensed suites these alternatives pages compare — Oracle NetSuite, SAP S/4HANA, Microsoft Dynamics 365 — are excellent at processes every company shares: statutory reporting, tax, payroll. They are expensive at processes only you have, because you pay for the platform and then pay again to bend it. A custom ERP on PostgreSQL inverts that: standard functions get integrated, and whatever differentiates you gets built once, in TypeScript you own.

### How do you compare vendors fairly on these alternatives pages?

3 rules. Every price, limit or capability we attribute to a named vendor carries a link to that vendor's own documentation, checked on the date shown. Anything we cannot source gets dropped rather than softened. And each of these alternatives pages states plainly who should stay put rather than move to a custom build — the Salesforce, Epicor ERP and Sage X3 guides all recommend the incumbent for a substantial group of readers, which is the only way a comparison is worth reading.

### What does a migration off a licensed ERP actually involve?

4 phases, and no big bang. An audit maps the schema, the customisations and every API integration. Extraction pulls records into a normalised PostgreSQL schema behind Drizzle ORM. A parallel run keeps both systems live with real-time sync until the numbers reconcile, phase by phase. Then a weekend cutover with a tested rollback. 8 to 16 weeks is typical for mid-market alternatives projects; heavily modified multi-entity estates run longer and get scoped separately.

### Do these alternatives cost less than the vendors they replace?

Past a certain size, yes, and below it, no — which is why every one of these alternatives pages names the crossover. A build cost replaces a subscription that rises at renewal, so the comparison is a one-off number against a growing recurring one. Under roughly 25 seats on a single standard application, most of the 10 vendors compared here — Odoo at 3 plan tiers, Zoho Creator, monday.com from $9 a seat, HubSpot — are cheaper. Above that, or where several ERP or CRM modules stack up, a custom system repays within 2 to 3 years.
