Monthly Bookkeeping
Monthly bookkeeping should make your life easier, not give you a new set of problems each month. If your numbers feel close but not quite right, or you keep putting off cleanup because you do not know where to start, you are not alone.
Perlinger Consulting, Inc. provides monthly bookkeeping and accurate accounting support for small business owners across Littleton, Centennial, the Denver Metro, and beyond. Our goal is simple: keep your books clean, current, and easy to trust.
Led by Glenn Perlinger, a fellow small business owner with 23+ years of experience, we help small business owners build a monthly process they do not have to babysit.
What Monthly Bookkeeping Includes
- Bank and credit card reconciliations
- Monthly categorization and cleanup
- Chart of Accounts organization so reports make sense
- Consistent month-end close process
- QuickBooks support to keep the file accurate
If you have been stuck in the loop of “we will fix it later,” monthly bookkeeping breaks that cycle. It keeps your records current and reduces the last-minute scramble.
Client Wins
One client came to us three years behind on reconciliations and feeling stuck. We cleaned up the transactions, reconciled the account, and brought the books current so the numbers were finally usable again.
Another client summed it up in a recent review: we revamped the last three years of their books, helped them save $7,200 per year by downgrading a CRM subscription, and made it easy to hand the work off so they could get their time back.
If you want your books to feel this clear again, start with a free consultation.
Who This Is For
- You want monthly bookkeeping handled consistently, not “when we can get to it”
- Your books are behind and you want a clean reset with a plan
- You use QuickBooks and want numbers that match reality
- You want bank and credit card reconciliations done correctly each month
If you read that and thought “yes,” this page is for you.
How Monthly Bookkeeping Works

We keep the process simple. First, we understand what is working and what is not. Then we fix the structure in the right order. Once the books are clean, we maintain them month-to-month so your reporting stays useful.
Not Ready for Monthly Bookkeeping Yet?
Sometimes the best first step is not ongoing bookkeeping. It is clarity.
That is where a QuickBooks Analysis comes in. Think of it like a diagnostic. We review your QuickBooks file, identify what is creating confusion, and give you a clear fix-first plan.
If you are not ready to commit to monthly service, Analysis is the fastest way to get clarity and a fix-first plan.
QuickBooks Analysis
Who it is for
- Something feels off, but you cannot pinpoint why
- Reconciliations will not match
- The Chart of Accounts is cluttered and hard to use
- Categorization is inconsistent and reports do not feel trustworthy
- You need a cleanup plan before you decide what to do next
What you get
- A written summary of what we find
- The priority order to fix it
- Clear recommendations for your next step: fix it, get training, or hand it off
Price: $200 (up to 2 hours)
If you decide you want us to complete the cleanup after the analysis, any additional work is billed separately and only with your approval.
A practical next step for small business owners
Frequently Asked Questions
Do you prepare or file income tax returns?
No. Income tax filing stays with your CPA. Our job is to keep your books accurate, organized, and reconciled so your CPA is not rebuilding your year.
Can you help if our books are behind?
Yes. Cleanup and catch-up work is common. We review what is currently in QuickBooks, identify what is missing or incorrect, and work through the backlog in a clear order.
Do you offer QuickBooks training too?
Yes. If training is the best next step, we will tell you. Some owners want bookkeeping handled start to finish. Others want to learn QuickBooks and keep it clean internally.
What is the fastest way to get started?
Book a free consultation. We will ask a few targeted questions and recommend the most sensible next step.
