I signed up with Carter Bookkeeping Services this year to handle the bookkeeping for both our UK and USA offices, and I have been extremely impressed with the service and expertise provided by Wendy and her team. Wendy’s attention to detail is exceptional. She is efficient, responsive, competitively priced, and always quick to answer questions. She also proactively reminds us of key dates and deadlines, which has been incredibly helpful for our business operations. I would have no hesitation in recommending Carter Bookkeeping Services to any business looking for reliable and professional bookkeeping support.

Wendy and the team at Carter Bookkeeping Services have been brilliant to work with. What really stands out is how approachable, organised and proactive Wendy is. She genuinely cares about helping clients understand their numbers rather than just processing them, and she goes above and beyond to make things simple and stress free. Her attention to detail is excellent, communication is always clear, and you can tell she is constantly looking at ways to improve systems and create a better experience for clients. If you are looking for a bookkeeper who is knowledgeable, trustworthy and genuinely invested in helping your business run better, I would highly recommend Carter Bookkeeping Services.

We moved to Wendy 6 months ago to manage the bookkeeping, CIS and VAT returns for our small plumbing company, having previously felt rather "lost" with a large corporate accounting firm. Definitely the right decision! Wendy is always efficient and helpful, keeping us on track with deadlines and happy to spend time explaining things (sometimes many times) to those of us less well-versed in accounting matters. Thank you Wendy!

I hired Wendy last year to complete my tax returns and it was one of the best decisions I could have made. As well as saving me a significant amount of time and money, Wendy was helpful, friendly and always got back to me quickly if I had questions. I will definitely be using Carter Bookkeeping Services again.

Where supplier payment processes go wrong

Small accounts payable errors can create expensive business problems

Supplier invoices often arrive through different inboxes, apps and team members. Without a consistent approval and recording process, information can be missed, duplicated or paid at the wrong time.

Duplicate invoices

The same invoice may be forwarded more than once, entered twice or paid again after a supplier reminder.

Missed due dates

Invoices can remain buried in inboxes or wait too long for approval, damaging supplier confidence and continuity.

Unclear approvals

Payments may be delayed or processed without sufficient confirmation when responsibility is not clearly defined.

Cash flow surprises

Upcoming supplier payments can place unexpected pressure on available funds when liabilities are not reviewed regularly.

Understanding the purchase ledger

What is accounts payable?

Accounts payable is the process of managing money your business owes to suppliers, contractors and other vendors. It covers the journey from receiving an invoice through to recording, approving, paying and reconciling it.

A well-managed purchase ledger gives you a reliable view of outstanding supplier balances and upcoming commitments. It also supports accurate bookkeeping, VAT returns, cash flow reporting and year-end accounts.

In practical terms, accounts payable helps you pay the right supplier, the right amount, at the right time.

The accounts payable cycle

1
Receive and record
Capture invoice details accurately
2
Verify and approve
Check the supplier, value and authority
3
Schedule payment
Plan around due dates and available cash
4
Reconcile and report
Match payments and confirm balances

Flexible supplier payment support

Our accounts payable services

We can manage the complete accounts payable process or take responsibility for selected tasks that are consuming too much of your time.

Invoice processing and verification

Supplier invoices are received, checked and recorded accurately before moving into the approval and payment process.

Purchase ledger management

We maintain an organised supplier ledger showing invoices, payments, credits and balances still outstanding.

Supplier payment scheduling

Payment schedules are prepared around agreed due dates, supplier priorities and your available cash position.

Cash flow visibility

Upcoming supplier commitments are reviewed so you have a clearer forward view of outgoing cash requirements.

Supplier account reconciliation

Supplier statements are compared with your ledger to identify missing invoices, unapplied credits and balance differences.

Duplicate invoice checks

Invoice numbers, suppliers, dates and values are reviewed to reduce the risk of duplicate or incorrect payments.

Accounting software integration

Part of complete bookkeeping

One connected view of outgoing finances

Accounts payable works best when supplier invoices, payments and credits are connected to the rest of your bookkeeping rather than managed in isolation.

  • Accurate bookkeeping records
  • Better information for VAT returns
  • Clearer cash flow reporting
  • Reliable year-end information
  • Consistent treatment of supplier credits

Frequently asked questions

Accounts payable questions

What do accounts payable services include?

Accounts payable services can include supplier invoice processing, approval tracking, purchase ledger management, payment scheduling, supplier statement reconciliation and duplicate invoice checks.

Will you make supplier payments directly?

The exact process is agreed with each client. We can prepare payment schedules and supporting information, while final payment authority remains subject to the access controls and approval process agreed with your business.

How do you reduce duplicate supplier payments?

We review supplier names, invoice numbers, dates, values and existing ledger entries before recording invoices or preparing payment information. Regular supplier reconciliations also help identify duplicates and discrepancies.

How does accounts payable help cash flow?

An accurate purchase ledger shows what is owed and when payments are due. This makes it easier to plan outgoing cash, prioritise commitments and avoid being surprised by a group of supplier payments at the same time.

Which accounting software do you use?

We work with Xero, FreeAgent and QuickBooks. Wherever practical, we use your existing system rather than creating unnecessary duplicate records or disconnected spreadsheets.

Can accounts payable be combined with other bookkeeping services?
Do you cover both Hertfordshire and Bedfordshire?

Yes. We support businesses throughout Hertfordshire and Bedfordshire, including Harpenden, St Albans, Watford, Bedford, Luton and Leighton Buzzard. We also work remotely with businesses elsewhere in the UK.

How much do outsourced accounts payable services cost?
