Bookkeeping Services in Littleton, CO
Perlinger Consulting works with Littleton small businesses to keep their books accurate, their QuickBooks set up properly, and their numbers in order when deadlines roll around. We take care of monthly bookkeeping, cleanup work, and QuickBooks support so you are not left second-guessing your financials.
If your bookkeeping feels messy, inconsistent, or constantly behind, it usually comes down to the same problems. Transactions are being categorized differently from month to month, accounts are not being reconciled regularly, QuickBooks was never set up correctly in the first place, or there is no simple routine to keep things on track. We focus on fixing the setup first, then putting a system in place that stays consistent.
Local focus: Littleton, CO
Bookkeeping Client Win
During the first reconciliation for a new client, we uncovered $5,000 that had been sitting in their books unnoticed. It came from transactions that needed to be matched correctly and cleaned up during bank and credit card reconciliations.
Once everything was organized, their reports finally reflected reality. This is the kind of clarity we bring to small businesses in Littleton.
Bookkeeping for Littleton Small Businesses
Littleton has a lot of owner-run businesses that move fast. Between job sites, client work, staffing, and sales, bookkeeping often drops until something forces attention. The problem is that messy books cost real money. They slow down decision-making, make cash flow harder to read, and turn a simple handoff to your CPA into a scramble.
We help Littleton small businesses get back to clean, consistent records. That starts with a clear monthly routine: transactions categorized the same way every month, bank and credit card accounts reconciled, and QuickBooks structured so reports reflect reality. From there, the goal is simple: keep it current, accurate, and easy to maintain.
How Littleton busineses run: Many local companies see seasonal swings and event-driven spikes around Downtown Littleton, the Southglenn area, Aspen Grove, and the Santa Fe corridor. When revenue jumps or expenses stack up, clean books make planning simpler and help you avoid surprises.
Colorado-specific readiness: When it’s time to hand things to your CPA, you should be able to do it without a scramble. We keep bank and credit card reconciliations up to date and your records organized so your CPA can file your income tax return using reliable numbers. If your business has sales tax or payroll reporting, we can support that side too, while your bookkeeping stays current month to month.

How our bookkeeping works in practice
If you want bookkeeping for small businesses in Littleton that stays consistent month to month, every bank and credit card account is reconciled on a regular schedule.
Accurate accounting starts with clean categorization and reconciliations.
Most Littleton business owners come to us because their books are technically “done,” but not reliable enough to make decisions.
When people search for bookkeeping services in Littleton, they are usually looking for someone who keeps records current, not someone who catches up once a year.
Clean books mean faster tax prep, clearer cash flow, and fewer surprises.
QuickBooks only works when it is set up correctly and maintained with a simple monthly routine.
If you are unsure where to start, we will review the current state, identify the highest-impact fixes, and map out the cleanest path forward.
Need the fastest win? Most Littleton clients start with a cleanup review, then move into a simple monthly routine that keeps things stable.

Littleton businesses deserve bookkeeping that is accurate, current, and easy to trust.
QuickBooks is a powerful tool, but it only works well when it is set up correctly and maintained consistently.
We help Littleton business owners clean up their QuickBooks files, fix structural issues, and put a straightforward monthly routine in place so reports start making sense again.
Some clients want to stay hands-on and understand what is happening behind the scenes. Others prefer to hand it off completely. We support both approaches, whether that means one-on-one guidance or full bookkeeping management.
Training is tailored to how your business actually operates. We focus on the features you use and skip the ones you do not. Many classroom courses spend hours on topics like sales tax, inventory, or payroll even when they are not relevant. One-on-one training moves faster, stays practical, and makes it easier to ask questions.

Littleton Bookkeeping FAQ
Do you prepare or file income tax returns?
Income tax returns stay with your CPA. We keep your books CPA ready with organized records and bank and credit card reconciliations, so your CPA can file without rebuilding your year. If you collect sales tax or run payroll, we can help you stay organized and ready for sales tax and payroll reporting. We don’t prepare or file income tax returns.
Do you only work with businesses in Littleton?
This page is for Littleton, and we work with many businesses here. We also support nearby areas across the Denver Metro and beyond. If you are close to Downtown Littleton, along the Santa Fe corridor, or just outside Littleton, reach out and we’ll tell you quickly if it’s a fit.
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 so the numbers become usable again.
Do you offer QuickBooks training in person?
Yes. Training can be online or in person depending on what you need. It is one-on-one and customized, focused on the parts of QuickBooks that actually impact your day-to-day work.
What kinds of businesses do you work with in Littleton?
We work with owner run small businesses across many industries, including contractors and service businesses. Most Littleton clients come to us for clean, accurate books, clearer reporting, and a monthly routine that stays consistent.
How do you avoid surprises at year-end?
By keeping bank and credit card reconciliations current and reviewing a short list of key reports monthly. If the file is accurate all year, year-end becomes a handoff, not a scramble.
