DueLark watches every QuickBooks Online company you keep, whether that is one business you own, several, or every client of your firm, and puts everything that needs a person on one list, worst first. One sign-in, every company; no switching between them to find out what is wrong. Then it does the asking, in the business’s name, and leaves the deciding to you. WHAT IT WATCHES More than twenty checks run on the books after every sync, each a plain rule you can read and turn off: a bank feed gone quiet, payroll that didn’t post, a likely duplicate, bills past due or due this week, undeposited funds sitting, a negative balance, invoices never sent or paid twice, customers you can’t reach, a scheduled bill or invoice that didn’t post, sales tax missed, a regular payee that stopped or doubled, depreciation not posted, cash short by a date. Each one shows the transactions behind it and what to do. GET PAID • Friendly reminders for unpaid invoices on a cadence you set, with the business’s name, logo and its own QuickBooks pay link • See each reminder before it goes, or let the cadence run; pause any customer any time • Reminders stop the moment an invoice is paid • Replies land in the app, and a customer’s “paid Friday” becomes a promise, not a chase RECEIPTS • Every charge over your threshold with no receipt gets asked of whoever used the card • Forward, snap or upload a receipt; DueLark reads it, matches it to the charge and attaches it in QuickBooks • Lost one? A signed statement instead W-9s AND 1099s • Which vendors need a W-9 this year, across every business, and who can be asked now • The signed form lands in the QuickBooks vendor record; the tax ID never touches DueLark MONTH-END CLOSE • A short checklist per business per month, and the close date set in QuickBooks when you say so • Changes made after a close, or before anything is closed, show up on the list YOU STAY IN CONTROL • Nothing goes to a customer or the books that you didn’t see first • DueLark writes to QuickBooks only on your tap: attach a receipt, file a W-9, categorize a charge, set a close date • Every change it made is listed, with who, when and what FOR FIRMS • Every client’s QuickBooks on one list, ranked by what needs you most; open any client with one tap • Every ask goes as the client’s business, never as your firm or as DueLark • A weekly summary to each client, so they see what got done FOR YOUR OWN BUSINESS • Connect your QuickBooks and DueLark follows up with your customers, chases your receipts and watches your books • Run more than one business? Each has its own QuickBooks, and DueLark watches them all on one list DueLark is for bookkeeping and accounting firms, and for owners of businesses on QuickBooks Online.
