North Mile BooksBOOKKEEPING SERVICES
Monthly Close Discipline for Duluth Small Businesses
North Mile Books runs the full bookkeeping cycle for local operators so the ledger stays current, invoices get followed up, and year-end work with your accountant starts from clean files.
Small businesses in Duluth often keep books in fits and starts. Sales go into one tool, receipts sit in a glove box, and payroll exports land in email once every other week. By December the gap between bank balances and the general ledger is wide enough that the accountant spends the first pass reconciling history instead of preparing filings. North Mile Books is built around a different rhythm: a fixed monthly close that treats bookkeeping as an operating system, not a year-end scramble.
We work with sole proprietors, LLCs, and small teams across the Twin Ports area. The engagement is service-based. You keep running the business. We own the chart of accounts structure, the bank and card reconciliation, invoice aging follow-up, mileage and expense capture, and the payroll feed into the books. At year end we package a handover your CPA can open without reverse-engineering your year.
What the monthly close actually covers
A monthly close is a sequence of checks that lock a period so later entries do not rewrite history. It is not the same as "entering receipts when you have time." For our clients the close runs on a calendar we publish at onboarding. Typical steps, in order:
First, bank and credit card feeds are matched to the general ledger. Every cleared transaction gets a category, a payee, and a link to source documentation when one exists. Unmatched items stay on an open list until they clear or get coded as owner draws, transfers, or corrections. Second, accounts receivable is aged. Open invoices older than the client's payment terms move into a follow-up queue. Third, expense reports and mileage logs for the period are posted, with vehicle records kept in a form that supports both ordinary deduction tracking and any mixed personal use. Fourth, payroll summaries from the client's payroll provider are journaled so wage expense, employer taxes, and liability accounts stay aligned with deposits. Fifth, balance sheet accounts that drift (prepaid expenses, deferred revenue, owner equity) are adjusted with short memos so the next period starts clean.
Only after those steps do we mark the month closed. Soft close means the team stops routine posting to that month. Hard close, used when a tax deadline or loan package needs a fixed cut, freezes the period and routes any late discovery to the current month with a clear note.
The point of a monthly close is not prettier reports. It is a ledger you can defend when someone asks what a number means six months later.
How a client month works, start to finish
Take a sample Duluth service firm: two owners, three employees, a job-costing need for materials, and a mix of card payments and net-30 invoices. Onboarding with North Mile Books begins with a chart of accounts rebuild. We map revenue by service line, split cost of goods from overhead, and set equity accounts so each owner's draws and contributions stay separate. Historical balances are brought forward only after a one-time reconciliation of the main operating account and the primary card.
During a normal month the client does three things. They send customer invoices from the shared system (or we issue them from templates they approve). They forward supplier bills and receipt photos to a dedicated intake address within a few days of the spend. They approve a short exception list we send mid-month for anything the bank feed cannot classify. Everything else sits with us.
Around day five after month end we complete reconciliation. Aged invoices trigger a written follow-up sequence the client can customize: a polite reminder, a second note with the original invoice attached, then a call script if the balance is material. Mileage entries from a log or app export post to the vehicle expense accounts with date, purpose, and miles. Payroll journal entries land after the final pay run of the month so the wage expense matches the bank. The client receives a short close package: profit and loss, balance sheet, AR aging, and a one-page notes file listing open items and any judgment calls we made.
That package is what makes year-end handover workable. In January we do not rebuild the year. We roll twelve closed months into a trial balance, attach support folders by account, and schedule a live handoff call with the client's accountant. Questions go to the notes file first. The accountant spends time on tax positions and elections, not on finding missing statements.
Team roles and how engagement starts
North Mile Books keeps a small bench so clients know who owns their file. A bookkeeping lead runs the monthly close and is the named contact for questions on coding and AR. A staff bookkeeper handles intake, receipt matching, and first-pass bank feeds. A senior reviewer signs off on each close package before it goes out, with attention on balance sheet integrity and payroll tie-outs. We do not replace your CPA or tax preparer. We prepare the books those professionals rely on.
Process for new clients in the Duluth area is straightforward. You request an intro call through the contact form on our site or by email. On that call we walk through entity type, current tools, bank setup, invoicing volume, and whether payroll is in-house or outsourced. If the fit is right, we send an engagement outline that lists systems access we need, the close calendar, and the documents for the initial rebuild. Kickoff is a working session: chart of accounts agreement, feed connections, and a first partial-month clean-up so the next full month can close on schedule.
Ongoing communication stays light by design. Clients get the close package each month, a mid-month exception ping when needed, and a quarterly review call to adjust categories or AR rules as the business changes. Urgent items (a frozen card feed, a large unapplied payment, a payroll mismatch) go through the lead by email or phone the same business day we see them.
