In November 2014, SMRT was given a single MAN ND323F demonstrator for trial purposes at the manufacturer's request.
Following a successful trial run, SMRT ordered 16 MAN ND323Fs which were delivered between August and November 2015 with tree guards pre-installed.

In late 2015, the Land Transport Authority ordered 60 units as part of the Bus Contracting Model (BCM) order.
Largely similar to the previous batch procured by SMRT Buses, these buses had some minor differences in appearance such as the omission of tree guards.
The final 10 units of this batch were equipped with USB charging ports.
The first 15 buses were painted in SMRT's corporate livery, while the rest featured LTA's green livery.
All of these buses are currently assigned to SMRT Buses.

Also in late 2015, a 12.8 m long custom built MAN ND323F with 3 doors and 2 staircases was built for the LTA, featuring an updated concept bodywork design.
Originally deployed to Tower Transit in 2017, it was transferred to SBS Transit in early 2018.

In September 2016, LTA ordered another 122 MAN ND323Fs which were put into service in 2017.
These buses contain similar specifications with the previous batch but with an updated bodywork design, with the first 30 units being based on the concept and the rest with an updated design.
These buses were assigned to SBS Transit, SMRT Buses and Go-Ahead Singapore, with most units in SMRT Buses replacing retiring Mercedes-Benz O405G bendy buses.

In late 2017, under a negotiated tender, the Land Transport Authority ordered 250 MAN buses, which were 150 MAN NL323Fs and 100 MAN ND323Fs, equipped with Euro VI engines and minor differences to the bodywork in the previous batch.
These buses were equipped with two wheelchair bays as compared to one in previous batches.
An option was excised in 2018 to procure an additional 150 MAN ND323Fs in this batch.
These buses entered revenue service in May 2018 and are currently assigned to SBS Transit, SMRT Buses and Go-Ahead Singapore for fleet additions and replacement of retiring buses.

In July 2018, a tender was awarded by LTA to ST Kinetics for the procurement of 111 MAN ND323Fs, which were delivered with subtle differences as compared to the earlier batches.
These buses entered service in March 2020, with the final bus expected to be delivered in 2021.
Similar to the previous batch, these buses will be assigned to various bus operators for fleet additions and replacement of retiring buses.

Following the successful trial of the three door MAN ND323F, the Land Transport Authority announced that 50 production batch 3-door ND323Fs will be procured along with 50 3-door Alexander Dennis Enviro500s.
These buses will be released on the roads in 2020.
