ERP guide

What is the best ERP system when you have outgrown your accounting software?

A custom ERP built by Black Badger is the best next step for a company of 50 or more employees that has outgrown its accounting software, because the ledger is rarely what broke and the spreadsheets around it are. Oracle NetSuite is the best product to move to if you would rather replace everything with one system.

The ranking, entry by entry

1 Custom build by Black Badger

Best for companies whose ledger works and whose operations do not

Outgrowing accounting software rarely means the accounting is wrong. It means orders, stock, jobs and approvals are being run in spreadsheets and email beside it. This is an outgrowing list, so the custom route goes first. Black Badger publishes this guide and builds these systems. We build the operations your team runs by hand today, connect them to the accounting package you already trust, and you own the code and every account with no per-seat fee.

Watch for. If month-end close itself is the problem, with several entities or complex reporting, a finance product is the fix. A build starts with discovery and a written scope.

How it charges
One-time build scoped in writing, then running costs such as hosting
Main limit
Needs a scoping call first, and suits companies of 50 or more employees

What a custom build involves, and how to ask about one

2 Oracle NetSuite

Best for growing companies ready to replace everything at once

NetSuite is the usual next product and ranks second. It fits a growing company that wants one cloud system across finance, inventory and order management, and its core platform covers all three plus tax. The cost of that choice is the change in how you pay. You go from a product with a public monthly price to a quoted annual license, with data migration, implementation and training listed by NetSuite as costs on top.

Watch for. Get the quote with every module you expect to need over the coming years as well as the ones for launch.

How it charges
Quoted annual license by modules and users
Main limit
Quote only, and each module is licensed separately
Checked

3 Microsoft Dynamics 365 Business Central

Best for companies that want the next step to keep a published price

Business Central ranks third as a step up. It keeps one thing a company leaving entry-level accounting software is used to, which is a price it can read. Essentials and Premium each have a published per-user price, paid yearly. For a company already on Microsoft tools the move is a natural one. The difference from what you have now is that Microsoft sends you to a partner to buy and set it up.

Watch for. Premium is required for manufacturing and service management. The Sales Order Agent and Payables Agent need Copilot Credits that are sold separately.

How it charges
Per user, paid yearly, bought through a Microsoft partner
Main limit
Manufacturing needs the Premium plan, and Microsoft sends buyers to a partner

4 Sage Intacct

Best for companies that have outgrown the accounting itself

Sage Intacct ranks fourth and is the right answer to one version of this question. If what you have outgrown is the accounting itself, with more entities, harder reporting and a longer close, Intacct is built for scaling businesses with complex accounting needs. Sage puts a typical fit above a stated annual revenue or at more than 20 employees. It does nothing for an operations problem.

Watch for. Decide which problem you have before you take the demo. Intacct is a finance system first and not a full operations suite.

How it charges
Quoted by sales to the size and needs of the organization
Main limit
Quote only, built around accounting for mid-sized firms

5 Odoo

Best for companies that want to add apps one area at a time

Odoo ranks fifth as a next step. It lets a company move in stages, since one per-user fee covers a wide set of apps and you can bring areas of the business on as you are ready. The Standard plan is billed per user, yearly. It ranks below the finance-led options because at more than 50 employees Odoo itself says you will usually need a partner, which changes the cost.

Watch for. A footnote on the pricing page applies a discount for 12 months to the initial users ordered. Budget from the regular price, because the first-year price does not last.

How it charges
Per user, billed yearly or monthly, one app free
Main limit
Mid-size firms usually need a partner, and Custom adds multi-company and Studio
Checked

6 Acumatica Cloud ERP

Best for companies about to add many light users

Acumatica is sixth. Entry-level accounting packages are usually bought by the user, and companies leaving them often plan to put far more people on the new system than ever used the old one. Acumatica does not price by user seats, which removes the per-user charge for doing that. It ranks here because a company used to buying software online will find the reseller-only, quote-only route unfamiliar.

Watch for. There is no public price list. The pricing page offers a custom pricing review, and a reseller handles the quote and the implementation.

How it charges
Quoted by applications and usage, not by user seats
Main limit
Quote only, sold through resellers, priced by resources and not by users
Checked

7 Fishbowl inventory and manufacturing

Best for product companies that outgrew only their stock tracking

Fishbowl ranks seventh and is the smallest step on this list. It adds inventory, warehouse and manufacturing control and connects to accounting tools such as QuickBooks Online, so the books stay where they are. Fishbowl lists Scale at a monthly rate with 10 users, billed annually, and quoted Advanced plans above that. For a company whose only gap is stock, it avoids an ERP project.

Watch for. A team of 50 or more lands on the Advanced plans, which need a demo request for a quote. Fishbowl does not replace a full finance system.

How it charges
Monthly rate by plan, billed annually, Advanced plans quoted
Main limit
Plans include 2 to 10 users, and the Advanced plans need a quote
Checked

How this list was ranked

This list is for a company that has passed about 50 employees on entry-level accounting software and now runs much of the operation in spreadsheets beside it. We ranked next steps by whether they fix what stopped working. This list assumes that is operations and not the ledger.

Custom is first here because this is an outgrowing list. It is second on our general list, behind NetSuite.

Questions buyers ask

How do I know my company has outgrown its accounting software?

To know whether you have outgrown accounting software, count the spreadsheets the business cannot run without. If orders, inventory, job costs or approvals live in workbooks that someone re-keys into the accounting package, you have outgrown it as an operations tool. If the close is slow because of entities and reporting, you have outgrown it as a finance tool. They are different problems with different answers.

Do we have to replace the accounting package to get an ERP?

No, you do not have to replace the accounting package to get an ERP. A full ERP such as NetSuite replaces it. Fishbowl and a custom build can both sit beside it and leave the ledger alone. Keeping a ledger your accountants trust removes the riskiest part of the move.

Should a 60-person company consider a custom ERP?

Yes, a company of that size should consider a custom ERP if its operation is specific and the team has grown around workarounds. Black Badger works mainly with companies of 50 or more employees for that reason. Such a company has an established process and enough at stake to justify owning the system that runs it.

What does moving to an ERP cost beyond the license?

NetSuite's own pricing guide lists data migration, implementation, training and support as costs beyond the license, and the same categories apply to every product here. Odoo states that implementation services are not part of its plan price. Ask for those figures in the first quote.
