Deciding which system does which job
Business Central can run payables on its own: purchase invoices, approval workflows, payment journals and electronic payment files. Companies add BILL because they want its invoice inbox, mobile approvals and payment network, where BILL collects vendor bank details and handles the disbursement. That split is reasonable, but only if each step has one home.
In the usual pattern, your team captures and approves invoices in BILL. The approved bill posts into Business Central as a purchase invoice. BILL pays it, and the payment lands against that invoice in Business Central. Business Central owns vendors and accounts and pushes them out. So BILL can only code bills to accounts and dimensions that exist.
The alternative, approving in Business Central and using BILL only to pay, is less common and harder to keep in step. We raise it when a company already relies on Business Central approval workflows tied to purchase orders and receipts.
Sync design, record by record
Where BILL and Business Central setups go wrong
- ✓Vendors created in both systems, then synced into duplicates with slightly different names
- ✓Bills approved in BILL and then keyed again by hand in Business Central
- ✓Payments posted straight to the bank account, so the combined debit on the statement never matches
- ✓Accounts renamed or blocked in Business Central without refreshing BILL's coding list
- ✓1099 vendor settings maintained in one system and forgotten in the other
- ✓Purchase order invoices approved in BILL before anyone checks the receipt
Connection options compared
BILL's own accounting sync
BILL keeps its own list of supported accounting systems. Confirm whether Business Central is on it for your plan and what the sync covers.
- ✓Least to build if it fits
- ✓Little room for custom rules
- ✓Read how it treats dimensions and payments
Third-party connector
Connector apps and integration platform templates from several vendors sync vendors, bills and payments between the two.
- ✓Compare how each applies payments to invoices
- ✓Confirm support for several companies
- ✓Another subscription to manage
API-based integration
BILL's developer API and Business Central's APIs, joined by code or an integration platform you already run.
- ✓Fits unusual approval or entity rules
- ✓Needs error handling and a named owner
- ✓You carry the upkeep as either API changes
What finance should check every week
Approved but unposted bills
In a Business Central Bill.com integration, anything approved in BILL but missing in Business Central is a sync failure. Fix it before it shows up on a vendor statement.
Clearing account balance
The BILL clearing account should empty as each withdrawal lands; a lingering balance is a timing gap or a missed payment.
Vendor balance comparison
Open balances for your largest vendors should agree in both systems. A difference means a bill or payment went one way only.
Rejected coding
Bills rejected for closed accounts or dimensions show where the coding list sent to BILL needs a refresh.
BILL and Business Central: common questions
Is it Bill.com or BILL now?
The company now brands itself BILL, while Bill.com is the earlier name that many invoices, contracts and colleagues still use. Both refer to the same accounts payable and payments service. When BILL appears as a vendor for its own fees, pick one name for the vendor record and use it consistently.
Do we still need Business Central payment journals if BILL pays vendors?
Not for vendors paid through BILL, but most companies keep payment journals for tax payments, wires and vendors outside BILL. The key rule is that you pay each vendor from one place only. We mark each vendor's payment channel, so nobody can pay the same bill twice.
How do BILL payments reconcile to the bank?
Through a clearing account: payments recorded from BILL credit the clearing account, and the actual bank debit clears it. Depending on settings, BILL may withdraw funds in amounts that cover several vendor payments, so matching payment by payment to the bank rarely works. Reconciling the clearing account keeps bank reconciliation simple.
More Business Central Bill.com integration questions
Can BILL work with several Business Central companies?
Usually yes, by setting each legal entity up separately in BILL and mapping it to its matching Business Central company. You should still book intercompany charges in Business Central rather than in BILL. We confirm how your chosen connector handles several entities before committing to it.
Should we use BILL at all if Business Central can pay vendors?
Only if its invoice capture, approvals or payment network save your team real effort, because otherwise it is one more system to reconcile. Business Central with electronic payments and approval workflows covers many companies well. If that describes you, we will say so plainly during scoping.
