Time is money, especially when it comes to invoicing. Invoice Manager dramatically reduces the time between completing work and receiving payment by automating the entire distribution process. Create professional-looking invoices directly in PDF format and automatically distribute them to designated email recipients with just a few clicks. What once took hours now takes minutes.
Invoice Manager
Coretime helps you raise accurate invoices quickly so you get paid faster. Invoice Manager automates sending invoices and statements, turning a slow manual process into a streamlined workflow. It lets you batch-email PDF invoices to multiple recipients, with exceptions sent to print automatically. You can also include backing sheets and statements to reduce queries and speed up payment.

Key Benefits That Drive Results
Speed – Invoice Faster, Get Paid Faster
Supporting Evidence – Reduce Queries, Increase Confidence
Custom-designed backing sheets can be sent with your invoices, detailing exactly what work has been done and when. This transparency reduces client queries dramatically, as recipients have all the information they need to approve payment immediately. Less back-and-forth means faster payment cycles and improved client relationships.
Credit Control – Automated Statement Distribution
Stay on top of outstanding payments with automated statement distribution that reminds customers what they owe. Regular, professional reminders keep your debtors healthy without requiring manual intervention from your team.
Draft Invoice Handling – Confidence Before You Send
Bulk produce Draft Invoices for a final sanity check before distribution. This quality control step helps you catch any errors or anomalies before they reach clients, maintaining your professional reputation and avoiding awkward corrections.
Custom Templates – Eliminate Post-Invoice Queries
Merge any information held in the Coretime database into your invoice layouts. This flexibility helps you provide exactly the information your clients need, formatted the way they prefer, reducing post-invoice queries and speeding up payment approvals.
Flexibility for Special Cases
Exclude nominated clients from bulk invoice runs when a more personal touch is required. Invoice Manager recognises that not all client relationships are the same, giving you the control to handle important Clients or sensitive situations appropriately.

Aircraft Leasing & Management
We have recently purchased Coretime through Onesys and were impressed with their responsiveness to our original enquiry and to our subsequent questions. The process for understanding what the software could do for us was efficient and straightforward, as was the administration involved in setting-up the account and finalising the agreement.

For us, the main benefit is that our system is now more user-friendly in terms of project managers being able to access information, such as seeing how a project is performing against budget. They can analyse how time is being spent and what proportion of it is earning fees – it’s easy to translate.

Since purchasing Coretime our time spent on administrative tasks, especially around invoicing has greatly reduced. We can also now respond to Client queries much more efficiently and with a more accurate, trusted response.
Overall the processes that we undertake using Coretime are much quicker and simpler and along with the benefits we’re now receiving in how we can report on our Project data using different parameters, we expect to see a return on investment within a year based on administration time saved.
