Quick Apply

$23 - $30 an hour

ERP systems
Attention to detail

Accounting and finance experience

Full Job Description

Looking for a quick, rewarding assignment where your bookkeeping skills can make a real difference?

Our client is seeking a skilled and dependable Bookkeeper to step in for a 3-week assignment and keep our accounting operations running smoothly. This is a great opportunity for someone who thrives in a fast-paced environment and can quickly take ownership of Accounts Payable and Accounts Receivable processes.

What You’ll Be Doing

You’ll start by getting up to speed quickly, then take the reins:

Week 1:

Learn the systems and processes through hands-on training
Partner closely with the current bookkeeper for a smooth transition

Weeks 2–3:

Take full ownership of AP & AR operations
Process invoices, payments, and collections with accuracy
Reconcile accounts and maintain clean, organized records
Handle a high volume of transactions confidently and efficiently

Why This Role Stands Out

Short-term commitment — perfect between roles or projects
Immediate start — get to work quickly
Consistent full-time hours (30–40/week)
Flexible morning start (7 AM – 9 AM)
Opportunity to step in, take ownership, and make an impact fast

What We’re Looking For

Experience in bookkeeping, accounting, or similar role
Strong knowledge of Accounts Payable & Accounts Receivable
Ability to learn systems quickly and adapt on the fly
Detail-oriented with strong organizational skills
Comfortable working independently after initial training

Bonus Points If You Have

Experience with ERP systems (distribution/accounting platforms)
Familiarity with Entree (NECS) ERP (not required)
Experience in high-volume transaction environments

Ready to Jump In?

If you’re a reliable, quick-learning bookkeeper who can hit the ground running and keep things on track, we want to hear from you.

Apply today and start making an impact right away!

Pay: $23.00 - $30.00 per hour

Work Location: In person
