NetLease Add-On module
NetSuite multibook lease accounting
Reporting one lease under two accounting standards manually invites errors and long nights at close.
Netgain’s NetLease Multibook add-on posts an additionalset of journal entries to your secondary book under a different classification and reverses the duplicated impact in your primary book, all inside NetSuite.













Common NetSuite multibook lease challenges
For companies with international subsidiaries or local reporting obligations, a single lease often has to be reported under more than one standard, such as U.S. GAAP ASC 842 plus IFRS 16, local statutory, or local government requirements. NetSuite's standard tools were not built to maintain two sets of lease accounting on one record, and the gap shows up in several ways.
NetSuite Multibook benefits
Multibook extends the NetLease you already run. There are no new interfaces to learn and no data leaving NetSuite. You turn on a second book, and NetLease handles the rest on the back end.

Two books, one record
Run a complete second set of lease journal entries for your secondary book directly on the same lease record you already use. No duplicate records, no separate process.

Effortless setup
Setting up a secondary book takes just two fields on the lease record: the secondary classification and the secondary book. NetLease takes it from there.

Automatic reversals
When you assign a secondary book, NetLease posts those entries and reverses the duplicated impact from your primary schedule, so your books never double-count the same lease.

GAAP and IFRS together
Report a lease that is operating under U.S. GAAP and financing under IFRS, or under any second standard such as local statutory or government requirements, at the same time. Multibook for NetLease is built for teams that close under more than one standard.

Change flow through
Modify, true up, or terminate the primary lease and every change flows automatically to the secondary schedule and transactions. Both books stay in step without extra work.

Side-by-side reporting
Flip between books in reporting to see your lease accounting under each standard, and view both amortization schedules side by side when you need to compare.

Multibook lease accounting software FAQs
Multibook is a NetLease add-on that posts a second set of lease journal entries to a secondary accounting book using a different lease classification. Multibook support has been part of NetLease since its early days; it was one of the original capabilities we built. It is most commonly used by companies reporting the same leases under more than one accounting standard.
Yes. NetLease treats true full secondary books and adjustment books in NetSuite the same, so posting to either type of NetSuite secondary book requires the Multibook Add-On for NetLease.
No. Multibook is an add-on to NetLease. It is priced as a percentage on top of your standard NetLease fee and is tied to your number of leases.
You set two fields on the lease record: the secondary classification and the secondary book. NetLease then posts the secondary book journal entries and reverses the duplicated impact from the primary schedule, so nothing is double-counted.
Yes, and this is the most common use case. A lease that is operating under U.S. GAAP is typically financing under IFRS, and Multibook lets you post and report both treatments for the same lease. Your secondary book can follow IFRS or another standard, such as local statutory or local government requirements.
NetLease supports one secondary book and one secondary posting schedule per lease record today. If you need a third book mapped differently, you can assign it to a separate lease record, though modifications and terminations would then be maintained on each record individually.
No. Multibook treats the secondary book as the same lease reported under a different standard, so modifications, true-ups, and terminations flow to both books together.
Yes. Reporting lets you flip between books, and you can adjust the amortization schedule saved search to view both books' transactions side by side.
The best option is software built natively on NetSuite, so your lease data and multibook entries never leave the platform. NetLease with the Multibook module calculates every classification on the back end, posts your secondary book automatically, and keeps both books in sync through every lease event, all inside NetSuite.
