Security Billing & Credit Control

A busy security company can deliver hundreds of hours of guarding, attend alarm calls and complete patrols across many sites in a single week. Getting that work onto the right invoices takes care. Small extras are easily missed, unusual charges need checking and your accounts team may need to ask the control room what happened before it can finish the billing.

GMS connects operational records with invoice preparation and credit control. Your team can review charges, resolve queries and transfer checked invoices to a supported accounts package. When an account becomes overdue, managers can see the position and decide what action is appropriate, with a clear record of payment promises and service decisions.

Security contracts often combine several services. GMS brings together charges for alarm response, patrol visits, keyholding, monitoring, service calls and agreed client billing lines. Guarding charges can also be included in the billing review, helping your team work through the services delivered to each customer.

Choose the billing period and review the relevant client or site. Charges are grouped so your accounts team can see what it is preparing, rather than starting with a collection of separate spreadsheets. Regular contract charges and additional work can be considered together, making it easier to spot something that needs attention before the invoice reaches the customer.

When a customer queries a charge, a useful answer starts with the service record. GMS uses recorded activity and the applicable charging arrangements to prepare billing lines. For an alarm response, that can include the attendance charge, time included in the visit and additional time on site. Service calls can include chargeable labour and parts.

For example, a customer might receive regular guarding and keyholding services, then need an overnight alarm attendance and a repair visit during the month. GMS helps your team review those different charges in context. The accounts conversation can begin with the work recorded and the agreed rates, giving both your staff and your customer a clearer explanation of the bill.

A missed clock-out or an unexpected rate can turn an ordinary invoice into a difficult conversation. GMS checks for issues such as unusual durations, repeated source charges and amounts that stand out from comparable billing lines. It highlights items for review and stops export where a blocking problem needs to be resolved.

Your team can investigate the warning while the supporting information is still close at hand. Where a chargeable service call needs a manually agreed price, that price must be entered before invoice generation. The supported accounts workflows also check the information needed for transfer, including relevant customer, billing and purchase-order details.

These checks help make invoice preparation more consistent and reduce avoidable corrections after billing. Your staff retain the judgement needed to decide whether an unusual charge is correct, needs explaining or should be changed.

Sometimes maintaining a good client relationship means exercising a little discretion. An officer may finish a response just beyond the time included in the agreed attendance charge. Where your company allows it, GMS supports a goodwill adjustment for a short overrun within your configured limit.

The adjustment is recorded against the response, including the time and amount waived. This gives your team a visible explanation for the billing decision and helps colleagues understand what has already been agreed when the customer next gets in touch.

GMS integrates with Clear Books and QuickFile to support customer records and sales invoice transfer. Your team prepares and checks the operational charges in GMS, then sends the invoices into the connected accounts package. This reduces rekeying and keeps the billing process closer to the work that produced it.

Accounting information can also be brought back into GMS to support credit-control review. Your operations and accounts teams can discuss an overdue customer using a shared picture of the outstanding position, with the latest reconciliation status visible.

Credit control becomes harder when the account position sits in one system and decisions about continuing work sit somewhere else. GMS brings outstanding balances and overdue information into a review process, using your company's configured thresholds to propose changes to a client's credit-control level.

Managers can review the proposal before applying a change. The distinction matters when a payment has just been made, an invoice is being queried or a customer has an agreed arrangement. If an accounting update is incomplete or fails, GMS flags that position rather than treating it as a completed review of the account.

A promise to pay should be available to the colleagues who need to act on it. Authorised users can record the promised payment date and amount, together with the reason and internal notes. They can also apply a temporary relaxation of the client's credit-control level, with a defined expiry.

This gives a manager a practical way to allow for an agreed arrangement while keeping it visible and time-limited. The team can see the underlying account position and the current exception, helping the next conversation start with what was actually agreed.

Decisions about overdue accounts need to take the security service into account. GMS lets your company set rules for when supported service categories require approval or become restricted. Permissions control who can change levels, grant an exception or queue a client communication.

Existing commitments can be brought forward for review, helping managers consider work already arranged and coordinate the next steps with operations. Decisions and reasons remain recorded, so the control room and account manager have a clearer basis for handling the customer consistently.

Bringing billing and credit control closer to your operation helps your team account for the work delivered, prepare clearer invoices and respond to overdue accounts with better information. It also gives managers a way to record the commercial judgement that sits behind a goodwill adjustment, a payment arrangement or a service decision.
