The problems we fix every day

Billing runs that take days

Every month, invoices are exported from the PSA and keyed into Sage or Xero one by one, while clients wait for their bills.

Clients and suppliers set up twice

Companies, contacts and suppliers live in both the PSA and the accounts, and slowly drift out of step.

Service teams can't see who has paid

Payments are recorded in finance but never make it back to the PSA, so account managers chase invoices that are already settled.

Margins hidden between systems

Agreements, projects and procurement costs sit in the PSA while invoices sit in the ledger, so profitability per client is guesswork.

How Zynk connects your PSA and your accounts

Your PSA is where the work happens: tickets, agreements, projects and procurement. Your accounting system is where the money is counted. Zynk keeps the two tightly in step, so each team keeps working in the system it knows while the records between them stay accurate.

  1. Clients and suppliers stay in sync. Companies, contacts and suppliers are matched between ConnectWise or HaloPSA and Sage, so nothing is set up twice and nothing drifts.
  2. Billing flows straight into the ledger. Unposted invoices, credit notes and agreement billing move from the PSA into Sage, Xero or your ERP with the right customer, nominal codes and tax treatment.
  3. Procurement lands where finance needs it. Purchase orders and supplier bills raised in the PSA arrive in accounts ready to match and pay.
  4. Payments come back to the PSA. Receipts recorded in finance return to ConnectWise or HaloPSA as invoice payments, so account managers can see who has paid.
  5. Batches are tracked on both sides. Accounting batches are marked as posted, so the PSA always knows what finance has already processed.

Every transfer is logged, and anything that fails is flagged with a clear reason before the next billing run. Zynk is low-code, so when your billing process changes, the integration changes with it, with minimal development time.

“Zynk are one of my favourite vendors to work with, and Zynk fills gaps that our customers need.”
